Flow-proportional, time-composited, and grab sample
estimation of nitrogen export from an eastern coastal plain watershed.
The species-accumulation curves for substrate classes and depth zones derived from the macrofauna grab sample
data for both locations did not stabilize toward an asymptotic value for observed data (Fig.
siliqua were followed over a three-year period on Banquereau (Eastern Canada) based on grab samples
(Gilkinson et al.
In 2000, the second author analyzed the results of 584 grab samples
that had been taken in 1999 from 580 ATUs by the Monroe County Health Department (MCHD).
A number of other prospects on the Rex-Duquet Property, several of them kilometre-scale, have also yielded grab samples
with significant grades for gold (up to 580 g/t Au), silver (up to 552.9 g/t Ag), copper (up to 4.4% Cu), tungsten (up to 0.87% W), molybdenum (up to 0.57% Mo) and rhenium (up to 1.44 g/t Re) (press releases of October 12, 2010 and February 9, 2012).
Channel samples are considered representative of the in-situ mineralization samples and sample widths quoted approximate the true width of mineralization, while grab samples
are selective by nature and are unlikely to represent average grades on the property.
are no more than indicators of probable performance at a particular moment.
The Bankfield which is located approximately 7 km to the East of the Rockstar vein, returned initial channel and grab samples
up to 39.8 g/t Au (grades ranged from detection levels to 39.8 g/t).
The potential of the prospect is for: (a) high grade, narrow vein gold as shown by the grab sample
assays; and (b) a more broad spread dissemination of lower grade gold in the veins and vein margins that may form an open-pittable bulk mining operation, as evidenced by the widespread gold reported in creek samples and drainages from the tenement.
The AnaTOC TOC analyzer has four grab sample
ports or can accommodate a 64-vial autosampler.
